FIVE BATHS

Five baths — from your room to a private bath

Korokan is one of the few inns in Arima with a hot spring source on its own grounds.

1. The open-air bath in your room
2. Kinpa-no-yu and Ginpa-no-yu — Korokan’s large baths, with indoor and open-air baths and saunas, facing Mt. Ochibayama. The open-air baths have the “gold spring” from our own source.
3. Ofuku-no-yu and Tamahoko-no-yu — open-air baths at our sister inn Yugetsusanso, along the Takigawa, the river that runs through our grounds. Cross Gekkobashi, the bridge, and walk through Yugetsusanso.
4. Tsuru-no-yu and Kame-no-yu — the indoor large baths of Yugetsusanso, a wooden sukiya-style building.
5. A private bath — included in this plan

The private bath — one 40-minute session free

Normally charged. Choose from:
Hinoki (1–8 guests) — all hinoki cypress, with a step-free entrance
Cave (up to 5) — surrounded by rock
Wine (up to 8) — sandstone, with a wine-scented bath additive

When you book, please tell us your preferred bath and start time, with a second choice.
Start times: 15:30 / 16:30 / 17:30 / 18:30 / 20:30 / 22:30

※ First come, first served, so we may not be able to give you your first choice. If we have not heard from you, we will ask at check-in; on some days every time may be taken.
※ The private baths are neither hot spring water nor open-air.

CUISINE

Dining — in your room

Dinner: a Kyoto-style kaiseki — seafood from the Seto Inland Sea and mountain produce from Tanba, lightly seasoned. Kaiseki is a sequence of small seasonal dishes, served one after another.
Breakfast: a Japanese set breakfast — simmered tofu, salmon and rolled omelette.
Both are brought to the low table in your room.
